Lystek Commissions Nutrient Recovery and Reuse Project in Minnesota

Lystek International Inc. from Cambridge, Ontario has announced that it has commissioned another installment of its low temperature Thermal Hydrolysis Process (Lystek THP®) at the City of St. Cloud, Minnesota, as part of the city’s nutrient recovery and reuse project.

The model project was partially funded through a Point Source Implementation Grant made possible by the Minnesota Clean Water Legacy Act (CWLA). The Lystek system is a key component of the project as it facilitates the recovery of valuable organic matter and nutrients from the city’s wastewater biosolids to create LysteGro®, a high-quality biofertilizer product that will be used  in the local agricultural market.

Lystek’s portfolio of solutions is based on its multi award-winning process which leverages years of science and research to tap into the value of biosolids and organics. Once considered waste, these materials are now viewed as recoverable resources for the production of high quality products, such as biofertilizers, green energy, and alternative sources of carbon.

St. Cloud is located in the Mississippi Delta river region and is the largest population center in the state’s central area. The Delta river region is known as the “Dead Zone” because it has been negatively affected by eutrophication due to run-off of nitrogen and phosphorus. The Minnesota CWLA is an ambitious plan that includes the provision of funding to local organizations for on-the-ground work to protect and restore lakes, rivers and streams and meet state water quality standards.

St. Cloud’s NEW Recovery Facility (Nutrient, Energy, and Water) serves a population of more than 120,000 from the city and surrounding communities of St. Augusta, St. Joseph, Sartell, Sauk Rapids, and Waite Park. The plant has a design flow of 17.9 MGD and features a biological nutrient removal system to help eliminate nutrient overloading into the local waterways.

Funding for this project also includes solutions from Ostara, another Canadian technology that is leading the way in struvite avoidance and phosphorus recovery in the wastewater sector, and the installation of biofuel storage to help optimize the fuel produced for the biofuel generator and reduced energy costs.
